A four-year-old sexually intact male dog and a seven-year-old sexually intact female dog presenting with heavy tick infestation were tentatively diagnosed with tick paralysis. Both dogs died due to respiratory failure. A number of ticks were observed in the head, ears, neck, trunk, and limbs of each dog. In these cases, a presumptive diagnosis of tick paralysis could be based on the presence of a species of tick known to cause paralysis combined with the absence of any other disease previously. Most ticks were identified as Haemaphysalis longicornis according to morphological features. Tick paralysis in dogs has rarely been reported in Korea.

A 14-year-old intact female, mixed dog was presented with hematuria and strangury. Mass in the abdominal cavity was seen on radiographs and ultrasound. On the cytological examination in the urethra, clusters of pleomorphic epithelial cell were found. Tissues of the urethra and the urinary bladder were obtained at the time laparotomy and determined the extent of the mass. Transitional cell carcinoma (TCC) of the urinary bladder was found in histopathologic characteristics. Urinary diversion after removal of a complete full section of the TCC in bladder wall was performed. Piroxicam, as a medical therapy for TCC, was orally administrated. Surgical operation and chemotherapy were selected with the goal of maintaining and improving quality of life.

This study investigated the frequency and distribution of canine patellar luxation (PL) in Bucheon city during January 2003 to December 2006. The 144 dogs with PL were analyzed according to grade, breeds, sex, age, body weight, and existence of concurrent cranial cruciate ligament rupture. Small breed including Yorkshire Terrier (31.65%), Maltese (33.09%) and Poodle (12.23%) had higher distribution of PL. Especially Yorkshire Terrier and Maltese had higher population of PL compared with other breeds. Most of them were diagnosed as II-III grade PL, and only a few dogs had grade I and grade IV PL. Small breed of body weight 2-3 kg (38.88%) had higher population of PL, and most of them were intact female (46.52%) and castrated male (38.19%) dogs. This study showed that clients recognized the necessity of the operation for dogs with PL well when the dogs are 6 months and 3 year-old, and have II-III grade PL. The reason that body weight of 2-3 kg had higher percentage of PL is related to the breeds. In analysis, intact female and castrated male dog had higher distribution of PL. The occurrence of concomitant cranial cruciate ligament rupture was 11%. Patellar luxation is therefore considered having an influence on cranial cruciate ligament rupture.

A two-month-old male calf weighing 70 kg with congenital metacarpophalangeal flexural deformity was referred to the Veterinary Medical Center of Chugbuk National University. The calf could not stand and walk normally that walked with the dorsal surface of the hoof with contraction of fetlock joint. The both forelimbs had been casted two times during 45 days before presentation. Midline of the palmar surface of the feltlock joint was incised to cut superficial flexor tendon, deep flexor tendon and interosseus muscle. Both forelimbs are healed well returned to normal function after tenotomy.
